Can't start RSD Lite

I'm trying to root my Droid for the first time and I've followed the instructions exactly onthe "SBF to root and to unroot" threadto the point where it says "Click the [...] next to the filename box and browse to where you saved the .sbf file you want to use and double click the .sbf file." However, the start button doesn't activate after I do that step so I can't start the process. Does anyone know how to fix this problem?
